Activated carbon eliminates odors. 3. The non-woven fabric captures impurities and hair. 4. The built-in pump sponge further filters debris to prevent blockages and damage. [Replace The Filter Regularly] - Every drop of water is filtered through multi-layer filtration to remove contaminants and provide oxygen-enriched, better-tasting water. To preserve filtering performance, it is recommended to replace the filters every 2-4 weeks. For multiple pets, clean the fountain and change the filter more frequently. [Optimal Usage] - Please soak the filter for 5 minutes and rinse before using to prevent activated carbon dust, which is not harmful to pets, from entering the water.
